FIELDVarious exemplary embodiments relate to lighting devices, for example emergency exit lighting.
BACKGROUNDEmergency units, such as exit signs and light fixtures, are commonly used in public buildings to indicate and illuminate areas such as stairs and exits in the event of a power failure. These fixtures typically have an emergency backup power system such as a battery that automatically turns on the emergency light when the primary power source is interrupted. Emergency lighting units are used in a number of commercial and residential settings.
SUMMARYAccording to an exemplary embodiment, an emergency lighting unit includes a housing. The housing includes a base having a first compartment and a second compartment. A first cover is positioned over the first compartment. A second cover is positioned over the second compartment. A lamp support is rotatably connected to the housing. A lamp head is rotatably connected to the lamp support.
According to another embodiment, a lamp assembly includes a lamp support having a stem, a first arm, and a second arm. A lamp head is rotatably connected to the first and second arms. A first conductor passes from the first arm into the lamp head and a second conductor passes from the second arm into the lamp head.
According to another exemplary embodiment, a lamp assembly for a lighting unit includes a lamp head and a light emitter. The lamp head includes a body, a front cover and a back cover. The body includes a front side and a back side. The front cover is connected to the front side of the body and the back cover is connected to the back side of the body. The light emitter assembly is positioned in the body.
The aspects and features of various exemplary embodiments will be more apparent from the description of those exemplary embodiments taken with reference to the accompanying drawings, in which:
Various exemplary embodiments are directed to a lighting system, for example, an emergency lighting unit 10 having a housing 12 and a lamp assembly 14. The lamp assembly 14 includes a lamp head 16 and a lamp support 18. The lamp assembly 14 is connected to and/or extends from a lower portion of the housing 12 and is adjustable with respect to the housing 12, allowing light emitted from the lamp assembly 14 to be aimed at a desired location.
As best shown in
In an exemplary embodiment, a stop 82, for example a substantially T-shaped projection, extends from the shaft openings 78. When the light assemblies 14 are connected to the lower cover 24, an anti-rotation bracket 84 is used to limit rotation of the lamp assemblies 14 in the shaft openings 78. As shown in

The foregoing detailed description of the certain exemplary embodiments has been provided for the purpose of explaining the principles of the disclosure and its practical application, thereby enabling others skilled in the art to understand the various embodiments and the various modifications that are suited to the particular use contemplated. This description is not necessarily intended to be exhaustive or to limit the disclosure to the exemplary embodiments described. Any of the embodiments and/or elements disclosed herein may be combined with one another to form various additional embodiments not specifically disclosed. Accordingly, additional embodiments are possible and are intended to be encompassed within this specification and the scope of the appended claims. The specification describes specific examples to accomplish a more general goal that may be accomplished in another way.
As used in this application, the terms “front,” “rear,” “upper,” “lower,” “upwardly,” “downwardly,” and other orientational descriptors are intended to facilitate the description of the exemplary embodiments of the present application, and are not intended to limit the structure of the exemplary embodiments to any particular position or orientation. Terms of degree, such as “substantially” or “approximately” are understood by those of ordinary skill to refer to reasonable ranges outside of the given value, for example, general tolerances associated with manufacturing, assembly, and use of the described embodiments.
